11. In the L'�tacq area the metamorphis has produces spotted hornfels with a grey colour. 12. At St . Ou�n's Bay the metamorphosis of greywacke has made hornblende-hornfels . 13. From diabases, basalts, andesites and other igneous rocks a third type of hornfels is produced. 14. Most ores are muscovite schist and mica phyllite, with some deposits in calc-silicate hornfels . 15. Hornfels , skarn and rocks derived from the lava dome ridge Lascar is constructed on form these xenoliths.16. However, the magma's heat was extensive enough to produce maroon hornfels nearly a mile away. 17. Exposures of hornfels on Goffle Hill are limited, but they occur readily in at least one location. 18. Lower pressure, normally contact metamorphism produces albite-epidote hornfels while higher pressures at great depth produces eclogite. 19. The rocks consist of shale and hornfels oriented toward the north and they shine for a while at sunset. 20. A contact aureole of 2.5 km thickness surrounds the batholith in the form of albite epidote hornfels .
